Information presenting apparatus and method for confirmed and tentative tracks

摘要

According to one embodiment, an information presenting apparatus receives each observed value from sensors, and maintains a track of each target by updating the track based on an observed value having a correlation with the track. A likelihood ratio for a tentative track, which has not yet been determined to be a track of a target, is computed and compared with an upper limit threshold. When the likelihood ratio is greater than or equal to the upper limit threshold, the tentative track is determined to be a track of a target. When the likelihood ratio is greater than or equal to a monitor threshold which is lower than the upper limit threshold, the tentative track is determined to be a monitor track. The information of the track and the monitor track are presented.
